Obese people showing signs of insulin resistance that portends diabetes improved their condition simply by avoiding the byproducts of dry heat-cooked or heat-processed foods, a U.S. study has found. High levels of “advanced glycation end products” (AGEs) not only cause pre-diabetes by increasing insulin resistance, they lead to brain changes similar to Alzheimer’s disease. For the study, one obese group was allowed to eat foods cooked by high-AGE grilling, frying or baking. The second group was told to avoid those methods in favor of poaching, stewing, or steaming. At the end of the study, the low-AGE group showed significantly improved insulin resistance, slightly decreased body weight, and much lower AGE levels in the body.
